Globin
The process of producing the formed elements of blood is called
Hemopoiesis

The reason it is more appropriate to call an erythrocyte a "formed element" rather than a "cell" is that erythrocytes

Only under certain conditions are anti D present, inherited independent of the ABO group
The "Buffy" coat of the middle layer of a centrifuged blood sample is composed of
Platelets and leukocytes
Which term best describes the function of blood when considering he presence of leukocytes and antibodies?
Protection
Erythrocytes exhibit a limited life span due to their ability to synthesize the proteins necessary to repair themselves
T
Globulins make up the second largest group of plasma proteins
T
Macrophages are the converted monocytes that phagocytize bacteria, cell fragments, dead cells, and debris
T
Simply put, antibodies are molecules on the lookout for antigens
T
The ABO and Rh blood types are inherited independently of each other
T
If agglutination occurs after a blood transfusion, it may indicate
The wrong blood type was used
Why is the name "thrombocytes" inappropriate for platelets?
They have no nucleus
Blood is correctly classified as a

Transportation
The leukocyte that releases histamine is the
basophil
Usually the least numerous of the leukocytes are the
basophils
The hemoglobin found in erythrocytes is able to chemically attach to
both oxygen and carbon dioxide
Which depicts the order of cell formation in erythropoieis?
c,a,e,b,d,f (myeloid, proerthythroblast, mature erythrocytes, normoblast, reticulocyte, nature erythrocyte)
the agglutinogens that determine the ABO and Rh blood types are
found on the surface of erythrocytes
One of the unhealthy effects of blood doping is to
increase the viscosity of the blood
t cells are a category of
lymphocytes
Usually the most numerous of the leukocytes are the
neutrophils
Which leukocytes are granulocytes?
neutrophils, eosinophils, basophils
Congenital hemolytic anemia is
when destruction of erythrocytes is more rapid than normal.
How many oxygen molecules may bind to a single hemoglobin
4
Which are characteristics of type A blood?
Anti B, will agglutinate with B, surface A
Which are characteristics of O type blood?
Anti- A, anti B, surface antigen O
The difference in concentration of various constituents in the plasma and interstitial fluid ensures that the constituents will

F
The antigen-antibody reaction is an example of the regulation function of blood
F
The blood type of a person missing the surface antigen D is Rh positive
F
The concentration of dissolved carbon dioxide is higher in blood than in interstitial fluid
F
The cytoplasm of an erythrocyte has numerous molecules called surface antigens that may elicit an anti body attack under the right conditions
F
When viewing a centrifuged blood sample, the erythrocytes will be on top.
F
The concentration of dissolved oxygen is higher in plasma than in interstitial fluid
T
Unused platelets last about 8-10 days before their contents are broken down and recycled
T
The leukocyte that is very active during a bacterial infection is the
neutrophil
One of the functions of blood is to regulate fluid levels in the blood. If too much fluid escapes from the bloodstream and enters the tissues, blood pressure will
Decrease
